Give an example of a function and explain why it is a function.

Hi names Sergeant von im here to help!

1) x2 (squaring) is a function.

2) x3+1 is also a function.

3) Sine, Cosine and Tangent are functions used in trigonometry.

4) and there are lots more!

Step-by-step explanation:

A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y. ... This is a function since each element from X is related to only one element in Y. Note that it is okay for two different elements in X to be related to the same element in Y. ;)

5,2

0,4

Step-by-step explanation:

the reason this is a function is because there are no repeating x values they each go to one y value

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
